I have found that if I don’t call FltReleaseContext enough times before my
MF the unload process hangs. Which I can understand but not expected. Isn’t
one of the ideas of having the Mini Filter manage these context so we could
get notified that we didn’t cleanup things like this when we unload rather
then hang?
It would be a nice test feature.

If you run with a DBG version of the Filter Manager, fltmgr.sys (which
should be in the kit you downloaded from the Beta Place website), it
does this check for you and will dump the list of leaked contexts to the
debugger screen.

Ken,
This hang is by design. We want you to get your context code right from
the beginning.
We are going to change the context leak detection code to be part of the
verifier so you don’t have to run a chk’d version of filter manager.
